These terms are applied to the subsidence of the inflammation and a restoration of the parts to their previous normal condition. This can scarcely take place except in acute and transient inflammations, as the occurrence of new-formation constitutes a more or less permanent lesion. In the case of acute inflammations, when the irritant ceases to act, the phenomena, so far as the blood-vessels are concerned, will soon cease, and there will remain to be dealt with the exudation and the alteration of the tissues. The exudation, so far as it consists of serous fluid and leucocytes, is, as a rule, readily absorbed. It is generally situated so as to be in immediate communication with the lymphatics, and the leucocytes, by their own movement, may pass into these. Where absorption is not so readily effected, the cells frequently undergo fatty degeneration, and this applies to other cells besides leucocytes which may be in the exudation. Cells which have undergone fatty degeneration readily disintegrate, and the resulting fatty matter is absorbed. In like manner, the fibrinous exudation may undergo disintegration, and be absorbed or discharged.
